I have heard of some apps that do it.

Any recommendations?

The following should both recreate & empty /var/log/messages:
/dev/null > /var/log/messages

Hi
You can type touch /var/log/messages.
the logfiles are trimmed by the cronjob logrotate.

You can, though, delete the name, and the file will then be deleted
as soon as syslogd is restarted or gets an SIGHUP signal. Of cours,
by deleting the name to the file no-one can open the file anyway.

If you delete the file and do "killall -HUP syslogd" then a new log file
will be created. Unlike syslogd on some other unix systems the version
included with linux will create the log files as needed.

You cannot.
However youcan start again
touch /var/log/messages.

Quote:>how do you trim logs down?

You do not. The usual way is to move the logs to say /var/log/messages.0
and then touch /var/log/messages.

It is built in to Redhat in /etc cron.daily/logrotate
